Definitions
- This invention relates to the treatment of phytate containing proteinaceous materials with trivalent aluminium to alter the physical, chemical and metabolic functional and nutritional values of the protein.
- the treatment is most advantageously conducted with solvent systems in which both the trivalent aluminium ions and the phytate possess sufficient solubility to measurably reduce the protein-phytate complex content of the proteinaceous material.
- organic solvents include alcohols (monohydric and polyhydric alcohols), ketones, ethers, aldehydes, esters, diethylene oxide, dimethyl formamide, dimethyl sulphoxide, and mixtures thereof.
- exemplary inorganic solvent systems include water, carbon dioxide, sulphur dioxide and mixtures thereof.
- the organic and inorganic solvents may be used separately or combined with one another with' or without non-polar solvents such as hexane and heptane.
- the trivalent aluminium ion treatment also effects an increase in the pl by approximately a 0.5-1.0 pH unit.
- Conventional isolation and fractionation processes are hampered by low yields below the pl even though the functional and nutritional values of protein products will be significantly improved by operating the manufacturing process at these more acid pH levels.
- the present invention overcomes this problem by permitting the manufacture to be conducted below the pl without sacrificing recoverable protein yields.
- the aluminium treatment of this invention permits the protein isolate, isolated protein fractions and enzymatically modified protein manufacturer to operate at pH levels below the pl level and obtain exceptionally high recoverable protein yields.
- the aluminium treatment converts the normally acid-insoluble protein-phytate complexes into an acid soluble protein product.
- the aluminium treated, water-soluble protein components are recoverable along with those proteins which are normally water-insoluble and complexed with the phytic acid and phytates.
- the ability to effectively recover essentially all of the acid-precipitable proteins results in a substantial increase in protein yields.
- the aluminium treatment yielded a 93% increase in water-soluble protein over the control and 88% more soluble protein than the sodium chloride-treated sample.
- the pH versus ml AICI 3 salts was plotted on standard graph paper and the intercept of the tangentials was determined as 11.3 ml.
- the total phosphorous content of the soy flour is 0.6% and the available phosphorous is 0.15.
- the weight percent phytate of the soy flour is calculated as follows:
